SPECIFICATION forming part vof Letters Patent No. 589,255, dated August 31, 1897. Application filed May 28, 1896. Serial No. 593,406. (No model.)

T all whom t may concern:

Be it known that we, JOHN S. FIELD and WILLIAM J. SHEDD, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Scrapers for Removing Snow, ttc., of which the following is a specification.

This invention relates to certain improve- Io ments in Scrapers for scraping the snow from ice-fields.

The object which we have had in view has been to adapt the scraper to be easily drawn after it has gathered a load, relieving the horses of some portion of the labor involved in moving the scraper from the field being cleaned to the point where it is to be dumped. To this end the scraper is adapted to be tipped back from its gathering position onto runners zo with which it is provided and which are secured to its under side, thereby raising the gathering edge away from the ice and enabling the scraper to be moved upon the runners to the dump.

A second feature of the invention relates to the construction by which the dumping is accomplished. In order to render this operation easy, the labor attending it is devolved upon the horses in the following manner:

3o The rear portion of the scraper is attached to the tongue and the tongue is movable longitudinally in its socket or keeper and is retained in it-s normal acting position while scraping and while moving the load by a latch, which can be released by the driver at will, so that when released the tongue moves forward in its keeper and the power of the draft is transferred to the rear edge of the scraper instead of the front edge, which re- 4o ceives the draft ordinarily. This transfer of 5o are longitudinal vertical sectionsshowin g'the apparatus indifferent positions.

In the drawings, A represents the scraper proper, armed with the metal plate or blade A at its forward edge and having raised ends A2 and back AB to enable it to retain the gathered snow. It is also pivotally connected at each end to side runners B .by pivots B. Upon the runners B is mounted the tonguesupporting frame, consisting of cross-beam C, uprights C', and braces C2 and C?. Draftrods D also extend from beamA C to the forward part of the scraper, as shown, so the power of the draf-t may be transmitted directly to the central portion of the scraper and the pivots B thus relieved of a part of the burden. In order to permit the various changes in position of the scraper, these rods are pivotally attached to the scraper in any suitable way-as, for instance, by forming eyes D in their ends, which interlock with other eyes D2 let into the scraper-and their upper ends pass through openings in the bent-up ends of metal straps or plates D3upon the beam and are free to slide forward in such straps, but cannot pullout of them, because of the nuts D4 upon the ends of the rods. -These nuts are adjusted so as to insure the proper action by the draft-rods and can-be changed whenever necessary.

E is a platform attached to the back of the scraper A and adapted to afford the driver a place on which to ride while the scraper is being moved from the point of loading to that of unloading.

The draft-tongue, by means of which the scraper is drawn, is shown at F, and F is the doubletree to which the horses are attached. The tongue is normally attached to the beam C, so that thepower is transmitted directly to the latter by means of devices which can be released when the dumping takes place, and consisting, preferably, of vertical plates F2, one at each side of the tongue and both rigidly secured to the beam, cross-bolts F3 uniting the upper edges of said plates, and a gravitating-latch F4, pivoted upon one of said bolts and engaging the notch or shoulder F5 in the tongue, as seen at Fig. 3,whenever the horses move forward. connected to the rear of the scraper by the frame G. ward end to the tongue by the pivot Gf and at its rear end to the scraper by the pivot G2, passing through elongated slot G* in the arm The tongue is also IOO This frame is attached atits for- G", projecting rearwardly from the frame and secured in an outstanding bracket attached to the scraper. A notched lever G is pivoted to the arm Gl and is adapted to engage the pivot G2, as in Fig. 2, when the scraper is positioned for gathering a load. ty this engagement the scraper is held in proper position to clear up the snow, and when a load has been gathered the driver releases the locking-lever G6 from the pivot and the scraper can then be tipped backward, so as to throw its weight upon the runners H, attached to its bottom, and lift the scrapingblade A out of contact with the surface of the ice. This movement will be understood from Fig. 3, in which the scraper is shown as resting upon the runners Il, and it carries the pivot G2 outward to the rear end of the slot G3. In this position the scraper with its load of snow can be easily moved from the ice-field, being cleared to the place of dumping, and the driver can ride upon the platform E while it is being moved without any danger of tipping the scraper any farther back, because the slot G3 prevents any further backward movement. At the same time also the scraper may be locked against tipping forward while it is being drawn to the dump by depressing the notched hand-lever Gr( to its lowermost position. (Indicated in broken lines at Fig. 3.) .ln this position the shoulder G'7 upon the lever acts as a lock to the pivot G2.

The tipping or dumping of the load is accomplished by the horses, preferably by the following devices: In a longitudinal groove J in the rear portion of the tongue is located a slide K, having an incline K', which while the snow is being gathered and the load is being moved to the dump is located under and a little in advance of the gravitating latch F4. lVhen the dump is reached, the driver, through the medium of the lever K2, moves the slide rearwardly, and thereby lifts the latch out of engagement with the shoulder F5 of the tongue, so that as the horses continue to move they will draw directly upon the frame G instead of cross-beam C, and as the tongue is now free to move longitudinally upon the cross-beam this results in a reverse or dumping operation, or, in other words, the turning of the scraper upon its pivots from the position shown at Fig. 3 to that shown at Fig. 4. The tongue slides forward in this movement7 while the runners and tonguesupporting frame remain stationary, and continues to move forward independently of the other parts named until the scraper has turned over as far as it can, or sufiiciently to insure the discharge of its load, and when the scraper has reached this position the whole machine again moves together. The extent of the independent movement of the tongue will be understood from a comparison of Figs. n a and 4:.

When the tongue moves forward to effect the du-mping, it at once carries the shoulder Ff in front of the pawl, and, during the rcmainder of the forward movement thc pawl, cannot engage either the tongue or the slide, because it is made broad, so it will ride during such remaining movement upon the straight unshouldered uppersurface of the tongue.

After the dumping the driver tips the scraper back to the position shown at Fig. 3 and drives back to the place being cleared. He then tips it to and locks it in its gathering position given at Fig. 2. lle also, by returning the lever K2, which is fulcrumed at K3, from its Fig. i position to that of Fig. 3, moves the slide K to its normal place in readiness for the next releasing operation, and the latch F4 is also allowed to drop into engagement with the shoulder F5 upon the tongue.

lfVhile our improved scraper has been devised,primarily,for use in scraping snow from ice-fields, it obviously may be put to other uses, and some of its most valuable features need no change to adapt it to'use in scraping dirt. Obviously, also, the construction we have shown may be changed in various ways without departing from the spirit of our invention.

The draft connections D ,whereby the draftframe is connected to the central portion of the scraper A, are desirably made rigid and unbending, as when thus made they do not bend under the weight of the snow or interfere in any way with the operation of the machine.

lVe claiml. The scraping-machine consisting of the scraper A, the runners, B, the tongue supported upon said runners, and movable longitudinally thereon, a latch and shoulder for attaching the tongue to its supports, a slide K and lever K2 for releasing saidla-tch from the shoulder, and a draft connection between the rear side of the scraper A and the tongue, substantially as specified.
